<strong>Internet Access:</strong>  Accessing the outside world using the ship's WiFi or internet lounge could become costly. A cheaper alternative is to ask the crew for the location of the best internet cafes in the port destinations.

<strong>Book While Onboard:</strong>  Most cruise ships have a booking agent onboard so you can book your next cruise without having to wait until the end of your current one. Cruise lines offer great rates and incentives to those currently at sea, so why not take advantage while you can.

<strong>Beverage Packages:</strong>  Cruise lines offer an 'unlimited' soda package which could yield great value if you plan on consuming a decent amount of soda during the cruise. If you have decided to smuggle your own alcohol onto the ship, the unlimited soda card is your ticket to tons of mixers which otherwise would add up pretty quickly depending on how much you're planning on drinking.

<strong>Public Transportation at Some Ports:</strong>  The cruise lines offer a variety of transportation options for each port, yet what they don't tell you, is that some destinations offer public transportation as well.

<strong>Overpack Certain Items:</strong>  When packing your batteries, chargers, and memory cards, bring double the amount of what you think you'll use. These types of items are extremely expensive on the ship or while in port, so don't risk having to purchase these items during your cruise. Hold onto your receipts at home and return whatever you don't end up using.
